mikesk8 Posted October 18, 2022 Share Posted October 18, 2022 Good afternoon, I have browsed the net and there are several posts regarding available BIOS versions (I think it was posted in few places by one of Atariage members): " Commonly found BIOS ROM checksums: Checksum 7931 GCE ROM. First Release. Title screen “GCE - ENTERTAINING NEW IDEAS”. Buzz. Checksum B796 MB ROM. Second Release. Title screen “VECTREX”. Buzz. Checksum 7ADB MB ROM. Title screen "VECTREX”. European Vectrex release. Fixed version of the built in game Mine Storm. No Buzz Vectrex. Different Printed Circuit Board (PCB) as compared to other Vectrex. Serial Number series 311xxxx. " I have an European (Dutch, 3GE) MB Vectrex with Buzz and with checksum B796, but with title screen “GCE - ENTERTAINING NEW IDEAS” and GCE 1982. I assume this is a common thing to have EU version with American BIOS. I also assume it is just a text label difference. What is your experience?
